What is Hiberfil.sys file?

  • Windows allows many power management schemes and Hibernate is one of them. Hibernate allows us to save current user configuration, such as programs, files, and folders, temporarily on the hard drive.
  • Hiberfil.sys file is responsible for managing computer hibernation, i.e., helping you get back to the last working state from hibernation.
  • When you select the hibernate button from the Start menu, the Windows manager will save the current state by creating a Hiberfil.sys file on the hard drive.

Are Sleep and Hibernation Different?

Hibernate and Sleep are two different power modes for Windows. Hibernate stores the current user configuration in the hard disk drive and cuts the power to the CPU. In comparison, the Sleep mode stores the current user configuration in the main memory RAM and doesn’t cut down the power completely.

Can I Delete Hiberfil.sys?

The answer to this question is “yes,” you can remove the Hiberfil.sys file from your Windows system if you disable the Hibernate feature.

  • The Hibernation power mode’s primary issue is that the files associated with it grow gradually over time.
  • A typical Windows system can have more than 10 GB of hibernation files and will grow over time.
  • Please note that if you are using the hibernate feature regularly, then deleting the Hiberfil.sys file won’t help as this file gets created every time you hibernate your system. For regular users, sleep is still a better option if you have limited hard disk space.
